The inspectors identified a non-cited viol … The inspectors identified a non-cited violation of Hatch Nuclear Plant Technical Specification 5.4, Procedures, with five examples for the licensees failure to establish, implement and maintain surveillance procedures for the high pressure coolant injection (HPCI) and reactor core isolation cooling (RCIC) systems. The deficiencies associated with the surveillance procedures precluded adequate evaluation of the as-found condition of those systems against acceptance criteria which serve as a basis for system operability. The licensee entered these five issues into their corrective action program under CRs 440646, 441302, 441333 and 441863. The immediate corrective actions included performing ultrasonic inspection of the surveillance test points which verified the absence of gas pockets. Interim corrective actions included implementing the performance of ultrasonic inspection of the surveillance test points immediately prior to venting the system in accordance with the surveillance procedure as a means to accurately quantify and evaluate the effects of any gas discovered. For the five examples identified, the failure to establish, implement and maintain adequate surveillance procedures to identify and evaluate accumulated gas in the HPCI and RCIC systems were performance deficiencies. The performance deficiencies were determined to be more than minor because they affected the procedure quality attribute of mitigating systems cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the performance deficiencies challenged the assurance that procedures used to perform surveillance testing of the HPCI and RCIC systems had adequately identified and evaluated the as-found condition of those systems as a basis for continued system operability. Additionally, if the performance deficiencies were left uncorrected, assurance was challenged that any future voids in the HPCI and RCIC system would be adequately identified and evaluated. The team screened the finding in accordance with Inspection Manual Chapter 0609, Significance Determination Process, Attachment 4, Phase 1 - Initial Screening and Characterization of Findings, and determined the finding was of very low safety significance (Green). These performance deficiencies were assigned a cross-cutting aspect in the corrective action component of the problem identification and resolution area because the licensee did not take adequate corrective actions in 2009 when weaknesses were identified with the surveillance procedures.entified with the surveillance procedures.
